Introduction:
International Steels Limited (ISL) Incorporated in 2007 in Pakistan with the vision to be the foremost manufacturer of flat steel products. Due to increase demand for production at the time ISL was the largest private investor in the value-added flat-rolled and coated steel industry in the country. The $165 million investment, with equity contributions from Sumitomo Corporation, JFE-Japan and the International Finance Corporation (A division of the World Bank) bought added impetus and confidence in the engineering and hi-tech manufacturing segment in country.
The Challenge:
International steels Limited has installed a natural gas burning power plant with 8 generators that generators 25 Mega Watt of power by co-generation. They need to efficient low sound performance fan for reliable circulated cooling air to prevent generators in a massive generator room. Install an energy-efficient ventilation system that minimizes sound levels, While looking for reliable ventilation equipment to meets specifications for air circulation/Exhaust in the building’s new generator facility, Project Managers wanted a product that would maximize airflow efficiency, while minimizing sound, This plant meet the needs of ISL steel complex and supplies surplus electricity to the Grid.Operate24 hours per day and required a large amount of ventilation to keep them cool. Sound levels from the generators are already high, so it was critical that the ventilation system operate as quietly as possible to maintain a safe working environment, the Plant having abrasive environment both due to Production and High salt contents in the air, near the Arabian Sea, ISL also demanded longevity and reliability in the working of the fans.
The Solution:
Greenheck offer their Model SBE -2L 60-50 with diameters of 60 inches for Exhaust and Model AX-160- 400-0614-K20 for Supplying Fresh Air to maintain optimum operating temperatures in the plant’s generator room. The fans are constructed with heavy gauge steel fabricated in continuously welded seams ensure a rigid body to withstand the heavy duty industrial Application also include standard air straightening vanes that create laminar flow in the air stream. (Note that Axial Fans are supplied with Permatector concrete Gray RAL 7023 Coating) for Outdoor use for abrasive environment.
The Results:
Greenheck Fans were selected to install in the generator Rooms and they perform as per the promised volume and successfully maintain Airflow for Supply & Exhaust to optimized operating temperatures in the plant’s generator room. The fans include standard air straightening vanes that create laminar flow in the air stream.
